ably assembling and subsequently advancing snperposed wm'k-sheets in typewriting machines having revoluble platens.

One ol' the principal objects of the invendevice which may either be used as a readily applied attachment to existing machines, or at least which will involve nothing beyond simple and inexpensive changes in such machines.

The work-sheets are provided with rows of pertorations along their side borders, and they are laid face down upon a suitable support. and there impaled upon gage pins by means of said perfor-ations. The gage pins extend in rows from front to rear along the sides of said support; although one row of gage pins may be omitted in some cases.

The leading edges of the sheets are nearest to the revolublc platen of the typewriter; the sheets in fact. occupying about the same positionsas they do when they are being insei-ted into a typewriter in the ordinary manner. the leading edge of the sheet being presented to the rear of the plat'en. the sheet being inverted so that the leading edge is at the bottom for this purpose,`\\'hile the rear side of tbe sheet faces the operator'.

On the face of the sheet the gaging perforations along its side are numbered, these numbers indicating the places for the lines of writing, and being usually at intervals equal to the line-spacing movements of the platen.

In practising the present iniprovements, the sheets are also provided with numbers on their rear faces, so that each perforation is numbered the same on both the front and rear face of the sheet. The numbers on the rear side appear in their natural positions when the sheet is being laid upon thc gage pins. the numbers on the rear side running from the leadingedge to the lin-al edge, but each number being inverted in relation to the corresponding number on the front face of the sheet, so that the numbers on both sides of the sheet are easily read in their natural positions whether the operator is looking at the front or rear side thereof.

From the foregoing, it will be understood that the operator needs only to lay the sheets upon the support or sheet-board, very much as he would in inserting the sheets in an ordinary typewriter, and that he may pla-ce any sheet in desired relation with any other sheet, by studying the numbers of the gage perforations.

After inserting the necessary carbon sheets, the operator withdraws the gage pins and advances the sheets to the platen without disturbing their relative positions, until they reach the position for receiving the first line of writing, which will fall upon the desired lines of the various sheets.

The advancing of the assembled sheets to the platen is preferably eected by turning an endless web upon which they are assemfbled, which serves as a sheet-supporting board while they are being assembled. This web may run over rolls, and may be connected to thel platen by any suit-able gearing, as for instance a sprocket and chain gearing, so that the surface speed of the web will equal the surface speed of the platen. The assembled sheets are held on the web by rolls, so that the sheets are properly advanced to and around'the platen, whereupon they are controlled by the usual feed rolls which run upon the bottom of the platen.

The rolls which cooperate with the web are releasable to give, clearance for assembling the sheets; and preferably a single motion both releases the rolls and restores the gage pins to protruding positions; a reverse motion causing a simultaneous retraction of the pins and movement of the rolls to positions to cooperate with the web. The same arrangement as to rolls and pins may be made at each side of the web.

Other Objects and advantages will hereinafter appear.

ln the accompanying drawings, Figure 1 is a perspective front view of the present improvements applied to the paper carriage 'of an Underwood front-strike typewriting machine. Fig. Q is a view to show the special feed'rolls retracted and the gage pins protruded at the left-hand side of the feed web; the severalv sheets being shown impaled upon the gage pins. Fig. 3 is aview similar to Fig. Q, but showing the pins withdrawn and the feed rollsl thrown into working positions. Fig. 4 illustrates the movement of the controlling lever from the Fig. I3 position toward the Fig. 2 position. Fig. .3 is a front sectional diagrammatic elevation of the invention in its preferred form, showing both feed rolls and gage pins at each side of the sheet assembling board. Fig. shows one of the work-sheets having perforation indicating Vnun'ibers on each of the front and rear faces thereof. ["ig. 7 a sectional side elevation showing the gage pins retracted and the `special feed rolls in working positions. Fig. 8 .is a perspective View showing the mounting of one of the sets of gage pins. Fig. E) is a perspective illustrating the superposition of two work-sheets. Fig. l() is a view similar to Fig. 5. but omitting one set of gage pins, and Showing both sets of special rolls cast olf to clear the assembling board for placing the sheets thereon.

The Vnderwood Y usually comprises types 1 which strike upon die front side of a platen 2- mouiited by means of an axle 3 and ends 4. 5, of a platen frame. said ends connected by a paper shelf o. and the axle usually haying hand wheels 'T for rotating the platen. The platen frame is yusually mounted upon a carriage, a part of which is .seen at 8. Fig. 1. and a line-space lever E) operates a slide 10 and pawl 11 to turn the line-.space wheel. 12 which is provided upon the platen axle.

The work-sheets 13. 14, 15 are laid upon an extension of the paper shelf G. this extension in the form of a web 16 which runs over upper and lower pulleys or rolls 17. 1S which are journaled by means of axles in a pair of side frames 19, 20 extending upwardly and rearwardly from the ends of the paper shelf and connected by tie-rods 21. The frame 'is supported upon the paper shelf o b v means of downwardly extend ingtongues 2-i which rest upon a transverse rod Q4 usually fixed to the platen frame and extending along behind the upper rear side of the paper `shelf. The tongues at their lower ends extend beyond this rodl 'J-l and bear up against the rear of the paper shelf. Shoulders or lugs :'25 on the tongues rest upon the rod Q4 to support the side frames.

Along the outer borders of the worksheets are evenly-spaced perforations QG by which the sheets are maintained in any desired relationship upon gage pins QT which extend in a row along one or both sides of the sheetsupporting web 16. said pins standing upon a bar QS which is carried upon the har 19, Fig. 1. and also upon the bar Q0.

- Fig.

The-holes QG are `numbered as shown in Fig. 1. on the rear sides of the sheets. and will be easily read by the operator when t \fpewriting machine the .sheet is viewed in the position in which it is naturally presented to the platen, namely. leading edge down and with its rear side to the ojierator. These perforation numbers .are therefore read from the leading edge to the opposite edge of the sheet, but stand upside down when the sheet is placed with its leading edge at the top. These numbers. however. correspond to the iuniilers seen at 2S) on the front of the worksheets. so that the operator. by regarding! the rear numbers. may ell'ect any desired relative position of the sheets.

A\fter placing' the necessary carbons between the superposed sheets. the operator swings inwardly projecting` handles and 31.,.thereby swinging down clamping or feeding rolls 32. lili upon the sides of the sheets. and also withdrawing the gage pins 2T. It will be noticed at Fig. S that the gage pin bar 2S is mounted by n'ieans of arms 34 upon a rock shaft at the rear end of which is an arm 30 that is engaged by a pin 37' projecting from an arm 38 that rises from a rock shaft 39 on which the arm 30 is fixed. so that when the arm 3S swings to the right the bar 2S is depressed and -the pins 9.7 withdrawn from the perforations in the .Work-sheets.

Each of the pressurel rolls 32, 33 is carried in a frame 4() swiveled at 41 between opposite arms 42 which are fixed upon a hub 43, the latter capable of limited rotation upon the rock shaft 39 or 44. as the case may be. In order that each roll 32 may bear against the paper independently. of the other rolls, each is provided with an individual spring 45 connected at one end to a collar` 46 on the rock shaft and at the other end engaging one of the arms 4Q. The independent movement of the arms 42 is limited by a pin 47 projecting from the rock shaft 39 through a slot 48 in the hub The rock shaft 39 is held in its effective position by means of a. spring detent 49 engaging a notch 5() in the hub of arm 3S. It will be understood that the structure at the .right-hand side of the frame corresponds to tha/t at the left-hand side throughout, so that the, description of one suiiices for both, although in some eases the gage pins at one side of the structure may be omitted. together with the corresponding bar 28 and shaft 35. A spring 51 is coiled around the gage pin shaft 35 to hold the pins 27 up in normal protriided positions and to return them to such positions when the operator swings the handle 30 to the. left to withdraw the feed rolls 32.

It will be observed that the upper and lower feed rolls 32 are directly opposed to the upper and lower pulleys 17, 18 over which the, wel) lo runs. An intermediate feed roll is provided between the reaches of the web to coperate with the middle roll .1.8. causes the web to be advanced at the yto receive the first line of writing.

same surface speed as the platen. and hence the sheets are advanced by the coperation of the web with the rollsl 32, 33 until they are brought under the control of the platen and the usual forward and rear feed rolls 56, 57, which run upon the under side of the platen. A\fter the sheets are brought under the control of the rolls 5G, 5T, the rolls 32 and need no longer be depended upon, and the sheets' are now advanced by turning the hand wheel T to be brought. into position Thereafter the writing may proceed line by line in the usual manner. If desired, the operator may then reverse the direction of rotation of the platen, and the web 1G, to return the sheets to positions to be impaled upon the pins again, and for this purpose the rolls may be lifted sutliciently to permit the introduction of the sheets between thesame and the web without causing the pins 2T to protrude above the side plates 19, 20. As soon as the sheets have been retracted far enough, the rollsl 33 may be castoff and the pins projected, and the sheets may then be pressed down upon the pins, and if desired one or more sheets may be withdrawn and other sheets substituted preparatory to advancing the re-assembled sheets to the platen. The retraction of the sheets in the manner stated is not, however, necessary in all cases. The movement of the frames t0 about their pivots 41 is limited by pins 60 on the frames extendinginto openings 6l in the arms 4'2.

IIt will be seen that by 'a very simple appliance the operator is enabled to place the sheets in any desired relationship to one another and then to preserve such relationvship while .the sheets are being advanced around the under side of the platen in the usual manner into position to receive the writing. To connect the t'wo shafts 39 and 44 to work in unison, there may be provided a transverse rock shaft 6'2 having on its ends beveled pinions 63, 64C to mesh with segments (35, 66 on the rock shafts.
